11mm Patent N9. 94,984, dated september 21,1869.

` FIRE-PLACE.

The Schedule referred to inV these Letters-Patent and making part of the same,

To all whom it may concern e it known thatV we, JAMES C. STRONe and LUTHER C.l MONEAL, of the city of Bualo, county of Erie, and State of New York,I yhave invented a new and improved Mode lof Supplying the Gases Evplved by Bnming Goalv in a Fire-Place with Air, from the back or sides of the replace, thus creating more perfect combustion, thereby'obtaining more heat from the sameamount of fuel, by consuming the gases 'that would otherwise pass up the chimney.

Also, a new and improved ,form of fire-place, composed of a deep space or chamber above and .in rear 4of the fire-basket, in combinationwith an inclined corrugated top, inclining upward fromA the back toward .the front; and we do hereby declare that thefollowing is a fulland exact description. thereof,reference letters'of reference marked thereon.

, Thenature of ourinvention consists in constructing -an air-chamber, E,attached'to the back or sides of l the firep1ace,which, being supplied with air by means of two' apertures D D, under the fire-basket, diseharg s i-t intothe back of the fireplace, by means of holcsF F, perforated through the back of the lireplace, thus supplying the gases evolved by the burn- `ing 'coa'l in the grate with suficient air to causeV their bein-g had to the accompanying drawings, and to the ,Toenable others to make and use our invention, we will proceed to describe its construction and operation, reference being hadto the accompanying draw vines Y We construct the air-chamber E, Figure 5, of iron or other suitable material, makingit of sui'cient depth to conduct the requisite' lquantity of air from the apertures D D to the perfor-ations F Fin the back of the fire-place (3,..Figure 3, the dimensions beingregulated bythe size of the tire-place.

The front` of this air-chamber being placed directly against the back of the lire-place C, as shown in Fignre 4, its top, back, and sides being completely enclosed with plaster, renders it` perfectly'airti'ght,'so -thaimone of the air` drawn through the apertures D D can escape, except through the perforations F F in `the back C of the 'fire-place, g. 3,-the heat causingV a continual passage of air into the apertures DD, through the air-chamber E into the rear of the fire,

through the perforations F F, supplies the gases in the rear of the fire with oxygen, thus causing their lperfect combustion, adding greatly to the amount of heat derived from the coal in two ways- First, by igniting the gasesfthat would Otherwise pass upthe chimney; and

:mizing fuel.

The air-chamber E or peIforationsF F can be attached to or made in the back or sides of the firechamber, asconvenience may dictate. t Y

We construct the fire-place or chamber of fire-brick, soapstone, or other appropriate material, with two cheeks A A, a back, C, and corrugated to'p B. p 1t is so constructed that the back 0 recedes from the `bottom toward the top, thus forming the chamber larger atV the top than at the bottom.

We construct an inclinedcorrugated top, B, ascend- 'ing' from the hack C toward the 'front `of the ,irechamber, by means of which the gases are very much retarded in their passage toward the chimncyh giving them more time to mingle with the oxygenjcoming through the perforations F F, and by its inclination aiding materially in. reflecting the heat into the room.

We claim as our invention, and desire to secure by Letters Patentl l. The fire-place A, withits sloping perforated back, in combination with the inclined corrugated top, constructed and arranged substantially as described.

2. In=combination with the subject-matter of the foregoing claim, the air-inlet passages D and F and chamber E.
